An electric vertical takeoff and landing (eVTOL) aircraft lift motor is disclosed. The eVTOL aircraft lift motor includes a stator connected to the eVTOL motor and a rotor coaxial within the stator. The stator includes an inner cylindrical surface and an outer cylindrical surface coaxial about an axis. The rotor includes a rotor cylindrical surface defining the axis, an air gap formed by combining the rotor cylindrical surface with the inner cylindrical surface of the stator, a magnet array positioned opposite to and spaced from the inner cylindrical surface by the air gap. The eVTOL aircraft lift motor also includes a first fan connected to and configured to rotate with the rotor. In addition, in some embodiments, the first fan is connected to an axial end of the rotor. The first fan may include a base platform, a roof platform, and a blade configured to direct air toward the air gap.
